actionscript-3 – 在SWFLoader上的Actionscript 3和Flex 4 Zoom

我似乎在SWFLoader上遇到了Zoom Gestures的问题.我有一个swf文件,这是一个家庭的平面图,我希望用户能够用两个手指触摸放大和缩小,下面的代码是我尝试过但不起作用.当我在触摸屏上进行测试时,当我将两根手指放在SWF中并尝试放大时,它不会缩放.

<s:SWFLoader id="floorplanImage" source="@Embed('assets/test2.swf')" width="100%" height="100%" smoothBitmapContent="true" horizontalAlign="center" />

这是我的动作3代码

import flash.ui.Multitouch;  
            import flash.ui.MultitouchInputMode;  

            Multitouch.inputMode = MultitouchInputMode.GESTURE;

            import flash.events.Event;

            public var selectedItem:Object;

            public function init(): void
            {
                floorplanImage.addEventListener(TransformGestureEvent.GESTURE_ZOOM,onZoom);
            }

            public function onZoom (e:TransformGestureEvent):void{
                floorplanImage.scaleX *= e.scaleX;
                floorplanImage.scaleY *= e.scaleY; 
            }

请帮忙！

UPDATE

我正在使用gestouch的路线,但是使用此代码,我无法放大或缩小SWF.使用常规图像可以正常工作,但除非我遗漏了某些东西,否则不能使用SWF.这是我的代码：

                            var transformPoint:Point = matrix.transformPoint(swfcontainer.globalToLocal(gesture.location));
                            matrix.translate(-transformPoint.x,-transformPoint.y);

            </mx:Script>

<mx:Image id="swfcontainer" horizontalAlign="center" width="100%" height="100%" />

当我使用常规图像时,它仍然无法正常工作…它不会让图像在缩放时保持中心,它不会让我放大,只有当我第一次使用它时,它会移动图像在右边.怎么这么难过？

请记住,我对Adobe Flex和Actionscript非常新,所以请尽可能清楚地回答.

_mLoader = new Loader();
 var mRequest:URLRequest = new URLRequest("drawer.swf" + "?nf=" + getTimer());

     private function onCompleteHandler(loadEvent:flash.events.Event):void
    {
          _mLoader.contentLoaderInfo.removeEventListener(flash.events.Event.COMPLETE,Starling.current.nativeOverlay.addChild(LoaderInfo(loadEvent.currentTarget).content);

    }

var _zoom:
    _zoom = new TransformGesture(this);
    _zoom.addEventListener(GestureEvent.GESTURE_BEGAN,onGesture);
    _zoom.addEventListener(GestureEvent.GESTURE_CHANGED,onGesture);

private function onGesture(event:org.gestouch.events.GestureEvent):void

        if (container_movieclip.scaleX!=1 || container_movieclip.scaleY!=1)

        }

        if (gesture.scale != 1)
        {
            var transformPoint:Point = matrix.transformPoint(container_movieclip.globalToLocal(gesture.location));
